BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct Chrysanthemum plant,botanically known as Chrysanthemum X morifolium, commercially grown as agarden Chrysanthemum plant, referred to as code number 65863 in U.S.Provisional Patent Application Ser. No. 62/708,405 and hereinafterreferred to by the name ‘Domsudipi’.

The new Chrysanthemum plant is a product of a planned breeding programconducted by the Inventor in Fareham, Hampshire, United Kingdom. Theobjective of the breeding program is to create new garden Chrysanthemumplants with numerous attractive inflorescences.

The new Chrysanthemum plant is a naturally-occurring whole plantmutation of a proprietary selection of Chrysanthemum X morifoliumidentified as code number 802358, not patented. The new Chrysanthemumplant was discovered and selected by the Inventor as a single floweringplant from within a population of plants ofthe mutation parent in acontrolled greenhouse environment in Fareham, Hampshire, United Kingdomin March, 2014.

Asexual reproduction of the new Chrysanthemum plant by terminalvegetative cuttings was first conducted in Fareham, Hampshire, UnitedKingdom in March, 2014. Asexual reproduction by terminal vegetativecuttings has shown that the unique features of this new Chrysanthemumplant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Chrysanthemum have not been observed under allpossible combinations of environmental conditions and culturalpractices. The phenotype may vary somewhat with variations inenvironmental conditions such as temperature, daylength and lightintensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined tobe the unique characteristics of ‘Domsudipi’. These characteristics incombination distinguish ‘Domsudipi’ as a new and distinct Chrysanthemumplant:

1. Upright to outwardly spreading and uniformly and broadly moundedplant habit.

2. Moderately vigorous growth habit.

3. Freely branching habit; dense and full plant form.

4. Uniform and freely flowering habit.

5. Medium-sized decorative-type inflorescences with light yellow towhite-colored ray florets.

6. Early season flowering habit, grown under natural season conditions,plants begin flowering in mid-August in the United Kingdom.

7. Good garden performance.

Plants of the new Chrysanthemum can be compared to plants of themutation parent selection. Plants of the new Chrysanthemum differprimarily from plants of the mutation parent selection in ray floretcolor as plants of the new Chrysanthemum have inflorescences with lightyellow to white-colored ray florets whereas plants ofthe mutation parentselection have inflorescences with light red purple-colored ray florets.

Plants of the new Chrysanthemum can be compared to plants ofChrysanthemum X morifolium ‘Domsudipi’, disclosed in a U.S. Plant Patentapplication filed concurrently. Plants ofthe new Chrysanthemum differprimarily from plants of ‘Domsuditwhi’ in ray floret color as plants ofthe new Chrysanthemum have inflorescences with light yellow towhite-colored ray florets whereas plants of ‘Domsuditwhi’ haveinflorescences with red purple to purple-colored ray florets.

Plants of the new Chrysanthemum can be compared to plants ofChrysanthemum X morifolium ‘Domsudiyel’, disclosed in a U.S. PlantPatent application filed concurrently. Plants of the new Chrysanthemumdiffer primarily from plants of ‘Domsudiyel’ in ray floret color asplants of the new Chrysanthemum have inflorescences with light yellow towhite-colored ray florets whereas plants of ‘Domsudiyel’ haveinflorescences with bright yellow-colored ray florets.

Plants of the new Chrysanthemum can also be compared to plants ofChrysanthemum X morifolium ‘Eventide White’, not patented. Inside-by-side comparisons, plants of the new Chrysanthemum differprimarily from plants of ‘Eventide White’ in the followingcharacteristics:

1. Plants of the new Chrysanthemum have larger inflorescences thanplants of ‘Eventide White’.

2. Plants of the new Chrysanthemum and ‘Eventide White’ differ in rayfloret color as plants of the new Chrysanthemum have inflorescences withlight yellow to white-colored ray florets whereas plants of ‘EventideWhite’ have inflorescences with pure white-colored ray florets.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph illustrates the overall appearance of thenew Chrysanthemum plant showing the colors as true as it is reasonablypossible to obtain in colored reproductions of this type. Colors in thephotograph may differ slightly from the color values cited in thedetailed botanical description which accurately describe the colors ofthe new Chrysanthemum plant.

The photograph is a top perspective view of a typical flowering plant of‘Domsudipi’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations andmeasurements describe plants grown during the winter in 14-cm containersin a glass-covered greenhouse in Fareham, Hampshire, United Kingdom andunder cultural practices typical of commercial garden Chrysanthemumproduction. During the production of the plants, day and nighttemperatures ranged from 17° C. to 21° C. and light levels averaged6,000 lux. Plants were grown under long day/short night conditions forabout five weeks (including propagation period) and then grown undershort day/long night conditions to induce inflorescence initiation anddevelopment. Plants were twelve weeks old when the photograph anddetailed description were taken. In the following description, colorreferences are made to The Royal Horticultural Society Colour Chart,Fifth Edition, except where general terms of ordinary dictionarysignificance are used.
